An experiment was carried out at Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2019-20 to study effect of different fungicides and calcium nitrate on quality shelf life Kinnow mandarin”. A spray carbendazim, copper oxychloride, mancozeb, propiconazole, nimbecidine, nitrate, their combinations were done ten days prior harvesting years old plants.
